In the new series, some time will have elapsed since we last saw the captain. A lot can happen in that time span, including kiddos. Would you like to see Picard with kids, married/unmarried? We tend to focus on him as an individual, but family brings out many new facets for an individual. As someone who counts "The Inner Light" among my top TNG episodes, it's something I'd be curious about. He'd be an old papa, for sure, but given that it's possible in the present, it'd be all the more possible in the future.
